Mere days ago, President Donald Trump was calling for a new “tone and civility” in politics after the arrest of a man accused of mailing pipe bombs to several top Democratic leaders. On Sunday, that was all out the window as he slammed Democratic donor Tom Steyer following an interview with CNN. Steyer was the intended recipient of one of the more than a dozen pipe bombs that were sent to Trump critics.

On Sunday, Steyer talked on CNN about the “political violence” that Trump and the Republican Party had created across the country. Shortly after the interview, Trump took to Twitter to blast the billionaire Democratic activist. “Just watched Wacky Tom Steyer,” Trump wrote. “He comes off as a crazed & stumbling lunatic who should be running out of money pretty soon. As bad as their field is, if he is running for President, the Dems will eat him alive!”

Just watched Wacky Tom Steyer, who I have not seen in action before, be interviewed by @jaketapper. He comes off as a crazed & stumbling lunatic who should be running out of money pretty soon. As bad as their field is, if he is running for President, the Dems will eat him alive!

Steyer, who has repeatedly called for Trump’s impeachment, hit back at the president on Twitter. “It is unthinkable that in the midst of the horrible political violence our president would resort to name-calling instead of repairing the damage to the fabric of our country,” Steyer wrote.

.@realdonaldtrump just tweeted at me in his typical insulting style after watching @CNNsotu. It is unthinkable that in the midst of the horrible political violence our president would resort to name-calling instead of repairing the damage to the fabric of our country.

During the interview with CNN, Steyer said that while there had been “bad behavior” by members of both parties, he noted Republicans are less likely to condemn those who say violent things. “You don’t find prominent Democrats who are leading chants with violent overtones like ‘Lock her up,’ ‘CNN sucks’ ― all the kinds of attempts to play to people’s strongest emotions,” Steyer said. “That creates an atmosphere where anything can bubble up and anything is bubbling up.”
